During the operation of photovoltaic power plants, issues such as component hot spots, loose wiring terminals, cable aging, inverter failures, and abnormal combiner boxes often manifest in the form of localized heating. If these heat hazards are not detected and dealt with in a timely manner, they can lead to a loss of power generation efficiency, and in severe cases, cause major safety accidents such as fires and equipment burns. To achieve rapid and accurate identification of heating hazards in photovoltaic systems, Suzhou LAILX has ingeniously created the handheld infrared thermal imaging device LX-F300, which uses professional thermal imaging technology, high-definition temperature measurement performance, and portable and easy-to-use design to safeguard the safe operation and maintenance of photovoltaic power plants.

The LX-F300 handheld infrared thermal imaging device is a professional industrial temperature measurement equipment that integrates infrared thermal imaging and visible light dual light fusion technology. It can capture the surface temperature distribution of objects in a non-contact, fast, and intuitive manner, convert invisible thermal distribution into clear and visible thermal images, and accurately locate abnormal hotspots. It is a powerful assistant for photovoltaic power plant operation and maintenance, electrical equipment detection, and industrial fault diagnosis. For the detection scenario of photovoltaic systems, LX-F300 can comprehensively cover the entire process of photovoltaic modules, string, combiner box, inverter, distribution box, cables, bracket grounding bodies, etc. It can quickly detect problems such as component hot spots, virtual connections of joints, cable overload, and internal equipment faults, achieve early detection and handling of hidden dangers, and prevent safety accidents from occurring.

In terms of core performance, the LX-F300 is equipped with a 320 × 240 high-resolution infrared detector, with a thermal sensitivity (NETD) of<0.05 ℃ @ 30 ℃, and has the ultimate temperature resolution ability. Even small temperature differences of 0.05 ℃ can be accurately captured, ensuring that subtle heat hazards are nowhere to hide. The equipment is equipped with a dual range temperature measurement mode, with a temperature measurement range covering * * -20 ℃~120 ℃ and intelligent switching from 0 ℃~650 ℃. It can accurately detect thermal spot hazards of photovoltaic modules at room temperature and is also capable of detecting high-temperature faults in electrical equipment, adapting to temperature measurement needs in all scenarios. The temperature measurement accuracy is as high as ± 2 ℃ or ± 2% (taking the maximum value), and the data is accurate and reliable, providing authoritative basis for fault diagnosis. At the same time, MagicThermal detail enhancement imaging technology * * is adopted to significantly improve the clarity and detail expression of thermal images. Abnormal areas have distinct contours and features, making it easy to quickly identify and analyze.

To meet the outdoor inspection needs of photovoltaic power plants, LX-F300 is designed with an ultimate handheld and portable feature. The whole machine adopts an ergonomic body, which is light in weight and small in size. It can be easily held with one hand and operated for a long time without fatigue. Equipped with a 2.8-inch high-definition color display screen, it has strong visibility under sunlight, and real-time synchronized display of thermal images, visible light images, and temperature data is intuitive and clear. The device supports free switching between three display modes: thermal image, visible light image, and fused image. It can overlay infrared thermal image with visible light image to accurately locate the position of the hot spot on the actual object, avoiding misjudgment. At the same time, it has multiple temperature measurement functions such as center point temperature measurement, automatic tracking of high and low temperatures, and area temperature measurement. With just one click, the target's highest temperature, lowest temperature, and average temperature can be obtained, making the operation simple and efficient.

In terms of practicality and functionality, the LX-F300 has a built-in large capacity storage space, supports hot image and video recording storage, and can review and compare historical data at any time for easy fault analysis and report production. Equipped with a USB data interface, it can quickly export stored images and videos to a computer, and with professional data analysis software, generate professional detection reports containing temperature data, thermal images, and fault locations. The power supply system adopts rechargeable lithium batteries with strong endurance, meeting the needs of all day outdoor inspections; The body has an IP54 protection level, which is dustproof, waterproof, and drop resistant. It can adapt to harsh outdoor environments such as sandstorms, rain, snow, high and low temperatures, and has full stability and durability. In addition, the device is equipped with a manual focusing function, with an imaging distance of up to 0.1 meters. Whether it is scanning the entire power station from a distance or detecting fine components up close, clear imaging can be achieved.

In the actual operation and maintenance of photovoltaic power plants, the application value of LX-F300 is particularly prominent. When detecting photovoltaic modules, the entire photovoltaic array can be quickly scanned, the hot spot components can be accurately located, the severity of the hot spot components can be determined, and faulty components can be replaced in a timely manner to avoid the risk of module burning or fire caused by the expansion of the hot spot; When detecting electrical systems, it is possible to quickly identify potential heating hazards such as loose wiring terminals, aging cables, and abnormal fuses in combiner boxes, inverters, and distribution boxes, ensuring the safe operation of the electrical system; Compared to the inefficient mode of traditional thermometers that require point by point detection, the LX-F300 can cover a large area in one scan, increasing detection efficiency by dozens of times and significantly reducing operation and maintenance labor and time costs.

As an important product of LAILX in the field of photovoltaic safety testing, the LX-F300 handheld infrared thermal imager has become an essential tool for photovoltaic power plant operation and maintenance personnel due to its core advantages of professional temperature measurement, high-definition imaging, portability, high efficiency, stability and reliability. It is not only a fault detection tool, but also a "frontline sentinel" guarding the safety of power plants. In the future, LAILX will continue to optimize product performance, deepen technological innovation, and provide more comprehensive and professional safety testing solutions for the photovoltaic industry, helping photovoltaic power plants operate safely, efficiently, and for a long time.
